Table 3.
Paired Samples Tests – Mean differences in time to peak EMG output (TTP) in seconds between muscle pairs during the SHKS and THKS. A positive value in Column 2 indicates that the first listed variable had a longer TTP than the second variable (was activated second). A negative value indicates the first listed variable had a shorter TTP than the second variable (was activated first). Statistically significant differences are denoted with an asterisk.

EMG=electromyographic; SHKS = single handed kettlebell swing; THKS = two handed kettlebell swing; GMAX‐L = left gluteus maximus during SHKS; BF‐L = left biceps femoris during SHKS; GMED‐L = left gluteus medius during SHKS; GMAX‐R = right gluteus maximus during SHKS; BF‐R = right biceps femoris during SHKS; GMED‐R = right gluteus medius during SHKS; BF‐T = mean activation of both biceps femoris muscles during the THKS; GMED‐T = mean activation of both gluteus medius muscles during the THKS; GMAX‐T = mean activation of both gluteus maximus muscles during the THKS.
